About

I am a first-year CS Ph.D. student at Texas A&M University, supervised by Prof. Wenping Wang and Prof. Xin Li. Now, I am working closely with Prof. Xinke Li at City University of Hong Kong. I received my B.Eng. from Southwest Jiaotong University (CN) and B.Sc. from University of Leeds (UK) with First-class Degree, Outstanding Graduates of Sichuan Province and Best Bachelor Thesis in 2024. Furthermore, Iā€™m a research intern at University of California, Merced, working with Prof. Lu Qi and Dr. Xueting Li, under the supervision of Prof. Ming-Hsuan Yang. Previously, I worked with Prof. Chongshou Li in SWJTU.

My research interests mainly lie in 3D vision and 3D generation. I am now focusing on 3D outdoor scene generation tasks, aiming to enhance the quality of generated outdoor scenes, make the generation process more controllable, and contribute to bridging the gap between synthetic environments and the complexities of the real world.

ECCV 2024 (Oral Presentation, top 2%)

This work uses a coarse-to-fine approach with scale-varied diffusion models to generate high-quality outdoor scenes. It successfully generates 3D scenes both unconditionally and conditionally, and it allows for easy fine-tuning across different datasets and generating infinite scenes.

Under Review, 2024

This work introduces a novel method that leverages scene graphs as an intuitive and user-friendly control format, enabling the generation of high-quality 3D outdoor scenes closely aligned with user-defined descriptions through a conditional diffusion framework.
